2)Conducting experiments

The experiment is the core part of the whole teaching process.Before the experimental operation,students must listen carefully to the teacher’s explanation of the key points and the difficulties they may encounter.Then students must put themselves into the means to use various instruments.They also need to understand the relevant specifications.They ought to put the experimental conditions(date,temperature,humidity,air pressure,etc.)down,then arrange and connect the equipment correctly based on the contents and methods of the experiment.For electromagnetism experiments,students can connect the power of the experiment instruments only after affirming the correct connection of the circuit.Then,students can complete the experiment based on the content and steps.During the experiment,students should carefully observe the experimental phenomena then put the experimental data down truthfully;moreover,it is never allowed to alter or plagiarize the given data.The teacher needs to be informed immediately in case of any difficulty or failure.At the end of the experiment,the experimental data should be submitted to the teacher to get reviews and signatures.The instruments should be put in order after these procedures.Students are only allowed to leave the laboratory only with the teacher’s permission.(https://www.daowen.com)
